So I was trying to recreate the look of Blizzard's achievements by using Adobe Photoshop Elements 11. I tried using Aorta (DDS Converter), and I managed to get a shine animation done correctly. However, when I went back to try it again with other objects, the transparency conversion ceased to work and replaced transparency with a white background. My png is transparent, so it seems that Aorta is causing the problem. I have a Mac, so I can't use Nividia's plugin.
Please tell me how to solve this problem, or if not, at least convert the files that I will shortly add to this post to dds.
Thanks in advance,
